In one of my prior experiments, I included the names of the snapshots I
created in a plain text file.
I used this file, and not the zfs list output to determine which
snapshots I was going to remove when it came time.

Hi Joe,
I use this script to delete my empty snapshots :
#!/bin/bash
NOW=$(date +%Y%m%d-%H%M%S)
POOL=tank
zfs snapshot -r [EMAIL PROTECTED]
FS_WITH_SNAPSHOTS=$(zfs list -t snapshot | grep '@' | cut -d '@' -f 1 | uniq)
for fs in $FS_WITH_SNAPSHOTS ; do
EMPTY_SNAPSHOTS=$(zfs list -t s
zfs list is mighty slow on systems with a large number of objects, but there is
no foreseeable plan that I'm aware of to solve that "problem".
Never the less, you need to do a zfs list, therefore, do it once and work from
that.
zfs list > /tmp/zfs.out
for i in `grep mydataset@ /tmp/zfs.out`;
I don't know if there's any easy way to delete them, but I can offer a

Hi there,

I would, if it is easy and you have enough room, and don't want any of
the snapshots, create another temp zfs file system and copy your data
there and destroy the current zfs file system. Then recreate it and
copy the data back. I don't know if there is
I got overzealous with snapshot creation. Every 5 mins is a bad idea.
Way too many.
What's the easiest way to delete the empty ones?
